My invention relates to marine toilets.

Animportant object of the invention is to provide apparatus of the abovementioned character, embodying the minimum number of moving parts,whereby the construction is extremely simple, cheap to manufacture,

and not liable to disarrangement.

A further object of the invention is to provide a single valve devicefor controlling the passage of flushing water, to the bowl, with simplemeans to control the action of the valve elements of the valve device.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

' In the accompanying drawings, forming a part of this specification,and in which like numerals are employed to designate like partsthroughout the same, a

line 77 of Figure 4.

In the drawings, wherein for the purpose of illustration, is shown apreferred embodiment of my invention, the numeral 10 designates a bowl,provided'at its bottom with a tubular outlet neck 11, connected with anoutlet pipe 12. The bowl 10 may be formed" of porcelain or thelike,while the outlet pipe 12 is preferably formed of bronze or anyother suitable non-corrosive material.

Arranged above the outlet pipe 12 is a ver Connected with the lower endof the cylinder is a T-coupling 14:, also preferably formed,

of bronze and suitably connected-with the outlet end of the pipe 12.- Adischarge pipe 15 is connected with the outlet end of the. T couplingand leads to any desired remote point. I V Mounted upon the top of thecylinder '13 isa head" or cap 16, preferably formed of bronze, equippedwith a stuffing box '17, receiving a reciprocatory plunger rod 18extendii ig into the cylinder 13. Rigidly connected with the free end ofthe plunger rod 18 is a plunger 19, of any well known or preferredconstruction, and equippedwith suitable packing. The plunger rod 18 andthe metallic parts of the plunger 19 are preferably formed of bronze. Itis thus seen that the cylinder 13 has communication, beneath the plunger19, with the bottom "of the bowl 10."

The numeral 20 designates a casing of a single flushing valve device;This casing is provided with a depending tubular neck 21, for connectionwith a pipe, not shown,

which leads to a source of water, such as to the oceanlevel. The caslng20 is preferably formed of bronze. This casing is provided upon one sidewith a horizontal tubular neck 22, externally threaded for engage- Yment within a screw-threaded coupling 23,

formed upontlie side of the cylinder 13, adjacent to'its upper end,whereby the'casing 20 is in communication with the cylinder upon theupper side of the plunger 19. I

The casing 20 is provided at'its top with a screw-threabled tubular'neck'24,'for engagement with a coupling sleeve 25, having an upperhorizontal flange 26,- to engage upon the top of'the flange 27, formedupon an elbow 28, which is preferably formed of bronze. Suitablepackings29 are arranged The elbow 29 is connected to a flushing pipe 30,leading into a tubular portion 31, which in turn leads into the upper'portiOn of the:

bowl.

The valve device casing 20 is provided upon its opposite sides, Figure6, with trunnions 32, upon which are pivotally mounted the'lower ends oflinks 83, which converge upwardly and are apertured for receiving aconnection, including a generally vertical arm 36 and a generallyhorizontal in37, which are preferably formed-integral with each otherand with-the lever. The rear end of the horizontal arm 37 is apertured'*and' is pivotally connected with the top' of the plunger rod'18 bymeans of apin 38 or the like. The lever 35 is preferablylpro- "vide'dwith an aperture 39. Shouldit be .erably formed of '43, preferablyformed of brass.

.erably formed of preferred tov have the lever generally horizontallyarranged, the horizontal arm v37 is disconnected from the rod 18 andlinks 33, and the lever is inverted and its forward end again pivoted tothe pin 34 while the pin 38 is passed through the aperture 39.

The outlet end of the T-coupling 14 is provided with a horizontal valveseat 40 having an opening 41 formed therein. The opening is adapted tobe closed by an upwardly opening check leaf valve 42, prefleather orother flexible carrying upon its top a weight The outlet pipe 12 isprovided at its outlet end with a horizontal valve seat 44, having anopening 45,. adapted to be covered by an upwardly opening leaf or flapvalve 46, prefleather or the like, and provided upon its top with aweight 47, preferably formed of, brass. As more clearly shown in Figures5 and 6, the valve casing 20 is provided in its bottom above and adjacent to the tubular neck 21 with an opening 48, surrounded by atapered or conical valve seat 49, adapted to receive thereon an upwardlyopening rolling or ball valve element 50, preferably formed of brass,composition, orany other suitable non-corrosive material. In. the upperportion of the casing 20 and adjacent to the lower end of the tubularneck 24 thereof is a web 51, having an opening 52 formed therein, and atapered or conicalva-lve seat 53 formed upon its top, for engagementwitha rolling or check ball valve element, 54. This check ball valveelement may be formed of brass, composition,

material, and

, or any other suitable material. Arranged above the check ball valveelement is a stop element 55, formed of bronze or the like, to limit theupward movement of the ball element, 54, but not perceptibly interferingwith the passage of water.

The numeral 56. designates a tubular bonnet preferably formed of. bronzeand having a reduced screw-threaded portion 57, engaging within ascrew-threaded tubular neck 58, formed upon the casing 20. A rotatablerodor shaft 59 extends through this bonnet and, is provided at its outerend with a handle or crank 60,. to turn the same. A

transverse pin 61 carried by the inner portion of the shaft 59 slidablyengages the bonnet 56 and prevents the shaft 59'from moving outwardly ina longitudinal direction. The shaft 59 is. provided at its inner endwith a pair of. diametrically arranged radially extending shiftinglingers or lugs 62, preferably formed integral therewith. One of theselugs is adapted to engage the lower ball element. 50 while the other lugwill simultaneously engage the upper ball element 54, thus retaining thelower ball element seated and holding. the upper ball element from itsseat.

The operation of the apparatus is as follows:

Upon the up stroke of the plunger 19, the contents of the bowl 10 arewithdrawn through the pipe 12 and enters the lower portion of thecylinder 18 and coupling 14, beneath the plunger, the valve 42 closingupon the up stroke of the plunger and the valve 45 opening. Upon thedown stroke; of the plunger, the valve 45 closes andvalve 42 opens and,the contents are discharged through the pipe 15, as is obvious. Upon theup stroke of the plunger 19, as above explained, ball valve element 50is seated, while ball valve element 54 is unseated and the watercontained in the cylinder 13 above the plunger 19 is forced through theflushing valve device and pipe 30 to the upper portion of the bowl Uponthe down stroke of the plunger, 19, ball valve element 54 is, seatedwhile ball valve element 50 is unseated and water is supplied to thecylinder 13, above the plunger 19 to fill the same. Y

It frequently occurs that the valves 42 and 4 may become wholly orpartly inoperative 9 without supplying additional flushing d that it isdesired to operate, the plunger water to the bowl, as such supply might.

cause the bowl to overflow. this situation, the handle 60 is turned forabout afourth of a revolutionand the fingers 62 will hold the lower ballvalve element seated while the ball valve element 54 is.

held from its seat... The seating of the ball valve element 60 cutso'lf, the further supply of the flushing water, and the retaining of theball valve element 54 unseated breaks the vacuum which might otherwiseoccur in the cylinder 13, above the plunger, thus permitting of the freeand easy reciprocation of the plunger.

Particular attention is called to thefact that I employ a singleflushing valve device embodying the two ball valve elements. Thisgreatly simplifies the construction of the apparatus. The ball valveelements being free to turn or roll upon their seats, tendto cleanthemselves and the seats, preventing cor roding. The arrangement of theball valve elements in close relation permits of the control of theiroperation by the single shaft 59.

it is to be understood thatthe form of my invention, herewith shown anddescribed,

is to be taken as a preferred example of'the same, and that variouschanges inthe shape, size and arrangement of partsv may be resorted towithout departing fromthe spirit of my invention or the scope of; thesubj'oined:
